The answer to your question about "normal auto fuel" seems to be: maybe J Be sure to read the final paragraph on page 94, where Chevron tries to scare us into not using mogas in aircraft engines.

I noticed in my AFM that Diamond allows fuel that meets the ATSM D4814 fuel standard as well as 100LL. I believe this standard allows up to 10% ethanol but the ATSM website charges $60 for the pdf file. Does anyone know if I am correct and that normal auto fuel pump gas is ATSM D4814 compliant. This would let me buy some of my fuel at my local gas station. Thanks for any help. -John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=425157#425157 http://www.matronics.com/Navigator?RotaxEngines-List http://www.matronics.com/contribution ________________________________ Message 2 _____________________________________ Time: 06:43:28 AM PST US Subject: RotaxEngines-List: Re: Rotax 912 Mogas - ATSM ethanol question From: "Roger Lee" ASTM is okay with auto fuel. As an example many of the SLSA aircraft are ASTM compliant and allowed to use auto fuel. ASTM isn't the same nor have the teeth that the FAR's do. -------- Roger Lee Tucson, Az.

Diamond Aircraft changed the language in the AFM for my Katana regarding fuel specification. If the fuel meets ASTM D4814 it is allowable which is great because ethanol free gasoline is hard to find. I'm lucky that there are 2-3 airports within 50nm that sell it. I understand that Rotax allows up to 10% ethanol. -John rob(at)hyperion-ef.com wrote: > Everything you might want to know about mogas can be found in this Chevron technical review ; http://www.chevronwithtechron.com/products/documents/69083_motorgas_tech_review.pdf (http://www.chevronwithtechron.com/products/documents/69083_motorgas_tech_review.pdf) Your specific question is discussed on page 45 of that document. > > The answer to your question about normal auto fuel seems to be: maybe J > > Be sure to read the final paragraph on page 94, where Chevron tries to scare us into not using mogas in aircraft engines. > > > Best regards, > > Rob Housman > Irvine, California > Europa XS > Rotax 914 > S/N A070 > Airframe complete > Avionics in progress > > > > -- Read this topic online here: http://forums.matronics.com/viewtopic.php?p=425166#425166 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
